Chelsea's title defence took yet another devastating blow this afternoon as a brilliant Liverpool side thrashed them 3-1 at Stamford Bridge.

The Blues have now lost six of their opening 11 Premier League games and they're currently sitting in 15th position, 11 points behind table toppers Manchester City.

Jurgen Klopp's Liverpool reacted admirably to falling behind in just the 4th minute as Ramires headed in an Azpilicueta cross to give Stamford Bridge hope of a positive result this afternoon.

But a wonderfully taken brace from Philippe Coutinho, his first goals since the opening day of the season, and then a deflected goal from substitute Christian Benteke ensured Liverpool went away with all three points.

So here's what we learned from such a brilliant game of football this afternoon...

Klopp is a tactical genius

When Liverpool's starting XI was announced, there were questions surrounding Jurgen Klopp's decision not to start with a recognised striker. It initially looked like it would backfire when Ramires scored, but it turned out to be a stroke of genius.

Klopp clearly felt Benteke wasn't quite ready for a full 90 minutes and would be better option from the bench, while Firmino could happily do a job in the 'false nine' role.

And he was right as Firmino shone throughout, with Liverpool by far the better side, and then Benteke coming off the bench to score Liverpool's third.

Liverpool were by far the better team today, and that should be credited to them rather than Chelsea's misfortunes.

Diego Costa needs help

A week rarely passes without Diego Costa getting involved in a bit of a scrap before getting away with it.

And today wasn't much different. The Spaniard should've seen red in the second half after he kick Martin Skrtel in the chest after fouling him, which referee Mark Clattenburg didn't see.

Costa's lack of goals this season appears to be down to him preferring to spend more time being violent towards the opposition. And some Chelsea fans have had enough of him, including these two...

Mourinho simply needs to be sacked...

Loads of Chelsea fans still don't think he should go, but there are even more who've simply had enough.

At any other club the manager would probably have been sacked by now, because six losses in your opening 11 games isn't good enough. Even more so when you're the defending Premier League champions and supposedly the best manager in the world.

The second half was evidence alone that the players don't appear to be playing for him anymore, which must be an alarming sign for Roman Abramovich.

He simply has to go if Chelsea want to recover and secure an unlikely top four finish.
